*LUBRICATING APPARATUS- zatente'oi 1 ans-5, 1906.

Application filed August 1, 1902. Serial no. 117,966.

To all whom it may concern: k

Be it known that I, JOHN F. McCANN-A, a citizen of the United States, residing at Chicago,*in the county of Cookand State of Illinois,-have invented certain new and useful Improvements'in Lubricating Apparatus, of which the following is a specification.

My present invention is concerned with a .novel. lubricating apparatus which I have devised primarily for use in connection with a locomotive-lubricating system of the'same general type as is shown' in my application erial No. 25,107, filed July 28, 1900, and which may be employed in connection with the lubrication of a stationary engine-or othermechanism in connection with which fluid is employed .to furnishthe power required for the operation of the pumps and is controlled from'the place where the mechanism is located that-automatically regulates their operation in accordance with the needs of the apparatus being lubricated Other features of'my invention are certain novel structures and mechanisms, all of which will be described at length in the body of the specification and specifically pointed out in t e claims annexed thereto.

My novel system and mechanism as applied to locomotive lubrication enables me to ubricate not only the cylinders, but also the ournal-bearings for the wheels, and that without any additional, complication of the mechanism other than the mere application of parts necessitated by the employment of a ump for each cylinder or bearing to be luricated.

Fig. 10 is view through the gravity vacuum-valve employed in connection with the apparatus, and Fig. 11 is a plan view of the same on the line'E E of Fig. 10

Before beginning a detailed description of the apparatus it may be stated that I have shown it as employed in. connection witha locomotive-engine and arranged to lubricate the journals 11, 1'2, 13, 14, and 15 of the wheels on each side of the engine, together with the driving steam-cylinder 16 on each side of the engine, the air-pump steam-cylinder 1.7, the air-pump 18, and the headlight dynamo 19, making a total of fifteen arts to be lubricated, .for which I employ ourteen pumps 20, which are exactly alike and associated together adjacent the reservoirs, and operated by a single yoke 21, the air-pump steam-cylinder 17 and the..headlight dynamo 19 being served by a single ump, their ipes 22' and 23, respective ein joined y the'union 24 to the pipe 25, whic leads to. the pump, a two-way valve 26, as best shown in Fig. 9, bein employed,

.so that the oil canbe thrown to t e airump steam-cylinder or to the dynamo, whic ever may be desired. v

1 The reservoir is, as best seen in Figs. 2 to 4, of a substantially rectangular shape, and consists of two parts, the lower main receptacle 28, which is of a U shape, surrounding on three sides, the smaller receptacle 29, formed in the central and'upper 'ortion thereof. The

receptacle 28 contains. t e lubricating-oil of the'proper grade for use in connection with the ]Ol1IIl&lS 0f the wheels, and itwill be seen that the ten pumps 20, devoted to these journalsare arrange in a row on the lower ortion of the reservoir, five on each side 0 the contains the finer grade of lubricatin -oil necessary for useupon the steam-cylin ers, and

The upper and smaller reservoir 29 loo it will'be seen that the four umps 20, which supply the three steam-c pump, and the dynamo are coated on'the side of the reservoir-adjacent to the receptacle 29 in a row with'two on either side of the center.

As best shown in Fig. 3, it will be seen that each pump is supported at the lower end I thereof by a block 30, which is provided with a shank 31, the inner end of which is screwed into a recess opening into the side of one of the rece tacles 28 or 29. Thegeneral olrtline of t e block 30 is circular, and the lower end thereof is closed by a circularplug 32,

- screwed into the under side thereof, so as to screwed in lace, a cap 37 is screwed onto the outside of t e lower portion of the plug 32, so as to seal the parts and make a neat finish. When the parts are assembled, an angular channel 38 is formed b the coincidence of channels formed in eac of the three parts 30, 32, and 36, so that the oil in the reservoir passes through the channel 38, past the valve 35 and up through the nozzle 34. The valveca'sing 39 is secured against the side of the reservoir above the block 30 by means of the pipe 40, which passes snugly through a pipe 41, which in turn passes through the front and rear walls of the reservoir and has its ends expanded or otherwise secured to said Walls to form a li uid-ti htpassage through the reservoir. T e en .of the pipe 40 is screwed into the valve-casing 39 and a nut 42, screwed onto the outer side of the pipe 40 and against the rear wall of the reservoir, serves to draw the valve-casing 39 tightly against the front wall of the reservoir. The pipe 40 thus supports the valve-casing 39 and at the same time serves as a discharge-passage for the oil from the pump. These pipes 40, as seen in Fig. 1, are extended ad'acent to the different parts to be lubricated, eing carried as far as ossible beneath the jacket of the engine to eep the oil from congealing in cold weather. The valve casin s 39 are of a generally rectangular sha e raving a preferably rounded front end an lprovided with the downwardlyprojecting en argement 43 from the bottom of the front ortion, which is exteriorl screw-threaded to receive the cap 44, which is em lo ed in holding the short tubular sightee glass 45 in position, the lower end of V which passes into the corres ondinglyshaped recess in the top of the bloc 30 and is secured in place by the ca 46, screwed onto the top of said block. T e valve-casing 39 inders, the airsired to g1ve an has the tubular pump-barrel 47, screwed'into the to of the outer portion thereof and a U- shape channel 48 is formedin the body of the casing, the pump-piston 49, which reciprocates through the barrel 47, passing into one of the vertical arms of the channel 48, which is above the sight-feed glass 45 and which opens into it throughthe valve-seat 50, which is closedby the valve 51, which is I The top of the other vertical arm of the channel 48 is closed by the screwlug 52,

preferably of the customary ball construction.

and the channel in the-end of the b ock 39, I

into which the pipe 40 is screwed, opens into this arm above the valve-seat 53,'which'is closed by the preferablyespherical check valve 54, so that it will be seen that as the pump-piston 49 is reciprocated' the oil will be drawn up from the sight-feed 'glass into the valve-casing and thence forced out through the pipe 40 to the art to be lubricated. The topof the pumparrel 47 is closed bythe customary stuflin -box 55 and cap 56. The pump-piston 49 as rigidly secured to it above the cap 56 a collar 57 which is preferably provided with a stem 58, by which the pum can be operated independently of the regu ar actuating mechanism when it is delpart an extra lubrication, as might occuri t e feed should be too small and the bearing become heated. As' previously stated, theoperation of all these pum s is controlled by the reciprocation of the yo e or cross-head 21, which is of the shape shown to accommodate itself to the various pumps and has the u per horizontalflan e 59 and the lower simi ar flange 60, these anges being rovided, respectively, with four and ten U-s aped recesses 61, through which pass the upper screw-threaded portions 62 of the pump-pistons 49. This yoke is supported and guided by the four studs 63, screwed into the front wall of the reservoir and passing through the elongated vertical slots 64, formed in the yoke. Above the flange 59 and 60 each pump-piston is provided with the set-nut 65 and a jam-nut 66, by which it is secured in position. As the yoke is reciprocated through a. uniform .vertical distance at each movement it will be a, parent that by adjusting the position of t e set-nuts 65,

which, together with the collars 57, form the Working gbutments to vary the amount of lost motion the length of stroke given to each pum -piston can be accurately adjusted to regu ate the amount of oil thatshall be fed to each bearing according to its needs.

The arrangement by which the oil is sulpplied to each of the pumps, together with t e sight-feed glass 45, furnishes an accurate indication to the engineer, so that he can determine the rate at which the oil is being pumped to each part and regulate it, as may be necessary. The chamber inside of the sight-feed glass 45 is filled with water, glycerin, or some other clear liquid that is heavier than the oil, and-as the oil is drawn from the chamber drop by drop the oil to take its place escapes drop by drop from the nozzle 34 and rises through the liquid the sight-feed glass, thus furnishing to the en in'eer an accurate and always-operating s'ig t-feed. As

the liquid in the slght-feed glass may gradually onto the end of the cock 67, the valve 69 opened, and as much of the liquid is then forced into the sight-feed chamber by operating the piston 71 as may be necessary to replace any liquid that is lost.

The immediate means by which the yoke 21 is reciprocated is best shown in Fig, 4, where itwill be seen that a' piston-rod 72 is secured at its top and toward its bottom to the flanges 59 and 60 by theset nuts or collars 73. The lower end of the rod 72 is provided'with the piston-head 74, which reciprocates in the cylinder 75, passing through the stufling-box 76, formed on the top thereof. The cylinder 75 is secured to the front plate of the reservoir 27 by the inlet and outlet pipes 77 and 78 in just the same way that the pipe 40 is screwed into. the pump-block 39 and passed through the pipe 41, and thus secures the block 31 in place. The bottom of the cylinder 75 is' closed by the screwthreaded plug 80. i i

The inlet and outlet pipes 77 and 78, as seen in Fig. 1, after passing out of the back of the reservoir are passed along the side of the engine, preferably underneath the jacket, as indicated b the dotted lines, and 0 en into the channe s 81 and 82, formed in t e block 83, cast into the body of one side of the cylindrical shell 84, mounted with its axis horizontal on the base 85, which is secured on the guide-bar 86 of the engine. The block 83 has formed therein between the channels 81 and 82 a third channel87, opening into the air, and these channels 81, 82, and 87 are connected by the ports 88, 89, and 90, respec tively, with the horizontal upper bearingsurface 91 of the block 83, upon which a slidevalve 92 reciprocates.

This slide-valve consists of the upper and lower plates connected by the .two vertical uprights 93, forming a rectangular aperture in which the eccentric 94 rotates to throw the valve first in one direction and then in the other. The bearing for the upper portion of the slide-valve is formed by the rib 95 projecting inward from the face of the cap 84, as does the block 83.

The underside of the slide-valve has formed therein the channel 96, which as the slidevalve reciprocates alternately connects the exhaust-port 90 with the inlet and outlet ports 88 and 89,- while the same ports are alternately brought into communication with the interior of the shell 84, so that the steam,

compressed air, or whatever form of fluid en ergy is employed passes through the pipes 77 and 78 and acts alternately on opposite'sides of the piston-head 74 to force the yoke 21 positively in both directions. The supply of fluid pressure enters through the aperture 97 from the pipe 98, which, as seen in Fig.5, is connected by a two-way cock 99 with the pipe '100, connected to the compressed-air reservoir 101 for the engine-brakes. or with the pipe 102, which, as seen inFig. 1, passes to the steam-dome 103, so that the lubricating apparatus can be actuated by live steam from the engine or by compressed air from the reservoir, as may be desired.

The movement of the slide-valve 92 and the conse uent operation of the pumps is controlled y the operation of the engine by the following mechanism: The eccentric 94 is mounted to rotate on the reduced end of a rock-shaft 104, the bearing for one end of which is formed in the cup 105, formed on the face of the cylinder 84. The eccentric 94 has rigidly secured on its rear end a disk 106, which has formed onthe rear face thereof at its periphery an annular series of ratchetteeth 107, which are engaged by a springpressed dog 108, which is pivoted, as at 109, between a pair of ears 110, projecting from a collar 111, screwed upon and rigidly secured to the portion 112 of the shaft 104, resting against the shoulder 113, formed on said shaft. As the shaft is rocked it will be apparent that the dog 108 will move the disk 106 forward with the shaft; but it is held from a rearward movement therewith by means of a spring-pressed detent-dog 114, pivoted at 115 between a pair of ears 116, projecting inward from the face of the disk 117, constituting the back of the cylinder and screwed into it. The sleeve 118, formed in the center of this disk 117, forms the other bearing for the shaft 104, the sleeve being provided with a stuffing-box 1 19 and cap 120 to prevent thev escape of the fluid under pressure from the cylinder 84. The rear end of the rock-shaft 104, as best seen in Fig. 5, has secured therecated at a rate corresponding to that at which the steam is supplied to the engine, thus giving a supply of lubrication proportionto valve-125, from which pipes or channels 126.

Fig. 1, lead directly to the part to be lubricated. The details of the preferred form of the avity vacuum-valve which I employ are fully illustrated in Figs. 10 and 11, and I do not herein describe and claim the same, as it forms the: subject-matter of my application, Serial No'. 81,242,-filed November 5, 1901.
